All-on-4 Dental Implants
All-on-4 dental implants use a strategically planned set of implants to support a fixed full-arch restoration for patients who are missing most or all teeth in the upper or lower jaw.

Understanding all-on-4 dental implants
All-on-4 is a full-arch implant treatment concept designed for patients who are missing most or all teeth in one jaw or whose remaining teeth have a poor long-term prognosis.
Instead of replacing every missing tooth with a separate implant, a full-arch bridge is supported by a smaller number of strategically positioned implants. Four implants are commonly used, although the final number and position depend on the patient’s anatomy, bone quality, bite, and treatment plan.
Angled posterior implants may allow the treatment team to use available bone more efficiently and may reduce the need for certain grafting procedures in selected cases. Bone grafting cannot be ruled out until the jaws have been evaluated with clinical examination and 3D imaging.
At Prestwicke Dental, full-arch treatment planning considers bone volume, gum health, facial support, smile design, bite forces, medical history, remaining teeth, and long-term maintenance. We also compare implant-supported treatment with conventional dentures and other restorative options.
Why patients consider this treatment
Potential benefits depend on your diagnosis, treatment goals, and individual oral health.
Replaces a full arch of missing or failing teeth
Provides a fixed alternative to a removable denture
Improves stability while speaking and chewing
Restores facial and lip support
Uses a coordinated implant and prosthetic treatment plan
May reduce the number of implants needed for a full arch
What to expect
A clear process helps you understand each stage of care.
Consultation and 3D Imaging
We evaluate your teeth, gums, bone, bite, smile, medical history, and treatment goals using clinical examination and 3D imaging when appropriate.
Digital Treatment Planning
Implant positions, prosthetic space, tooth arrangement, bone availability, and the planned restoration are coordinated before surgery.
Implant Placement
The planned implants are placed, and any non-restorable teeth are removed when included in the treatment plan.
Temporary and Final Teeth
A temporary fixed restoration may be possible in selected cases. After healing, the final full-arch prosthesis is fabricated and adjusted.
How we approach all-on-4 dental implants
Treatment recommendations depend on the diagnosis and condition of the affected teeth and tissues.
Full-arch treatment begins with diagnosis and prosthetically driven planning. The implants must be positioned to support the planned teeth, not simply placed wherever bone is easiest to access.
The term All-on-4 commonly refers to a restoration supported by four implants, but some patients may benefit from a different number of implants. The final design is based on anatomy, bone quality, restorative space, bite forces, and risk assessment.
When the implants achieve appropriate stability, a temporary fixed bridge may sometimes be attached shortly after surgery. Immediate fixed teeth are not guaranteed and depend on implant stability, bone quality, bite, and overall clinical conditions.
The temporary restoration is designed primarily for healing and appearance. Patients generally need to follow a modified diet and avoid excessive chewing forces while the implants integrate with the bone.
After healing, records are taken for the final restoration. Tooth position, shade, facial support, speech, bite, hygiene access, and esthetics are evaluated before completion.
Even though the replacement teeth cannot develop cavities, the implants and surrounding tissues require daily cleaning. Special brushes, floss aids, water flossers, and professional maintenance may be recommended.
Full-arch implant treatment is not maintenance-free. Screws, restorative teeth, acrylic, ceramic, or other prosthetic components may wear, loosen, chip, or require repair over time.
Is this treatment right for you?
All-on-4 treatment may be considered for patients who need full-arch tooth replacement and want a fixed alternative to traditional removable dentures.
You are missing most or all teeth in one or both arches.
Your remaining teeth have a poor or uncertain long-term prognosis.
You want a fixed restoration rather than a removable denture.
You have adequate bone or can complete any recommended grafting.
Your medical health allows implant surgery and healing.
You are committed to daily hygiene and professional maintenance.
What results may look like
Full-arch implant treatment may restore a complete smile, improve stability during chewing and speaking, and provide greater confidence than a loose removable denture. Results depend on implant integration, bone support, bite forces, hygiene, medical health, smoking status, and regular maintenance.
Individual outcomes vary based on oral health, diagnosis, treatment selection, healing, habits, and maintenance.
Care centered on clarity, comfort, and long-term health
Every treatment plan is personalized around the patient rather than a one-size-fits-all approach.

Recommendations are based on your oral health, concerns, comfort, and long-term goals.

Common questions about all-on-4 dental implants
These answers provide general information. Your visit will address your specific oral health and treatment needs.
What does All-on-4 mean?
It describes a full-arch restoration commonly supported by four strategically positioned dental implants. Some patients may require a different number of implants based on their anatomy and treatment plan.
Can I receive teeth on the same day?
A temporary fixed restoration may be possible when the implants achieve adequate stability and other clinical requirements are met. Same-day fixed teeth cannot be guaranteed before evaluation and surgery.
Do All-on-4 implants feel like natural teeth?
They provide a stable, fixed replacement and typically feel more secure than removable dentures, but they do not reproduce every sensation of natural teeth.
Will I need bone grafting?
Some patients can avoid extensive grafting, while others still need site development. The decision depends on bone volume, implant position, anatomy, and treatment goals.
Are the teeth removable?
The full-arch prosthesis is generally fixed and removed only by the dental team when maintenance or repair is needed.
How long does the complete treatment take?
The timeline varies according to extractions, implant stability, healing, grafting, and the final restorative process. Full treatment commonly requires multiple appointments over several months.
What can I eat after surgery?
A soft or modified diet is generally required during early healing to reduce stress on the implants and temporary restoration.
How do I clean under a full-arch bridge?
Special floss, interdental brushes, water flossers, and other hygiene aids may be recommended to clean beneath the restoration and around the implants.
How long do All-on-4 restorations last?
Implants and prosthetic components may provide many years of service, but longevity depends on integration, hygiene, bite forces, smoking, health conditions, and professional maintenance.
Can the bridge break or wear out?
Yes. Teeth and prosthetic materials may chip, wear, loosen, or require repair or replacement over time, especially in patients with strong bite forces or grinding habits.
Is All-on-4 better than dentures?
It usually provides greater stability and a fixed design, but it also involves surgery, healing, maintenance, and a larger financial commitment. The best option depends on the patient’s health, anatomy, goals, and budget.
Can smokers receive full-arch implants?
Smoking may increase the risk of complications and implant failure. Individual risk should be discussed before treatment.
